TRADING MODEL AND PRODUCTION ANALYSIS OF RESIDENTIAL PHOTOVOLTAIC GRID-CONNECTED TWO-STAGE ENERGY
Aiming at the problem of how to realize the friendly interaction between the residents side and the grid side,this paper establishes a two-stage optimization model for grid connection.In the first stage,the optimization goal is to minimize the cost of electricity for residential users.In the second stage,the optimization goal is to minimize the average return period under the addition of photovoltaic-energy storage grid-connected operation.Firstly,the multi-user scheduling model is simplified by means of probabilistic statistics,which is equivalent to the sum of four types of characteristic user scheduling and solved by PSO algorithm.Secondly,a residential home energy management system and energy trading mode are proposed,and the trading mode is put into production analysis.The results of the example analysis show that the two-stage optimization model dispatching system can effectively reduce the peak and adjust the valley,and save the electricity cost.
